Its where I'd start though - check the valve is still a one-way-street and check the delivery rate from the pump - nothing to scientific, just make sure its giving a good surge of fuel at cranking. Then you'll know you've got carbs that are full within seconds of starting to crank and you (we) can go from there.....

Great info mate thanks.
Do you know if the coils earth themselves through the chassis via their mounting plates?
I ask as I had a possible brainwave - the chassis has been powder coated, the main earth point is clean but I just bolted the coils right back into place when I re-built it. I presume this could make the spark weak?
